Wet Woodland
Native trees — alder, willow, downy birch — on permanently or seasonally wet ground. A UK priority habitat that combines high biodiversity with flood-water storage and carbon-rich wet soils.
Carbon and evidence
Carbon Sink & Ecosystem Services
A living landscape element — a carbon sink and provider of ecosystem services, not a manufactured product. Its value is measured by sequestration and biodiversity, not embodied carbon, and it must never be netted against a product’s A1–A3.
Carbon Sequestration
Sequestered — carbon removed from the atmosphere
trees plus carbon-rich wet soils; wet conditions complicate simple accounting
Source: Woodland Carbon Code
Indicative and highly variable by species, size, soil and context. Sequestration is slow and reversible — it is not equivalent to avoiding an emission and must not offset embodied product carbon.
Biodiversity Net Gain
wet woodland is a UK priority habitat and high-distinctiveness
Source: Defra Biodiversity Metric 4.0
England requires a 10% Biodiversity Net Gain; distinctiveness is one input to the habitat unit calculation.
Water / SuDS
stores flood water and slows flows

Ecosystem Services
Establishment & Maintenance
planting on wet ground; low input once established
Read This Honestly
- •Sequestration is slow, uncertain and reversible — it un-banks if the plant dies.
- •Needs genuinely wet ground; not for free-draining sites.
